The structural properties of metamagnetic shape memory alloy Ni 40Co10Mn34Al16 were investigated by X-ray powder diffraction measurements in the temperature range from 283 to 473 K and magnetic fields up to 5 T. With increasing temperature from 283 K, the alloy undergoes the reverse martensitic transformation from the tetragonal Ll0-type structure with the lattice parameter at = 0.3853 nm and ct = 0.3299 nm into the B2-type cubic structure with the lattice parameter ac = 0.2924 nm at As = 383 K. At 408 K (>As), we directly observed the field-induced reverse martensitic transformation.
